A number of approaches have been used to design journal-level taxonomies or ontologies, and the scholarly research and practical application of these systems have revealed their various benefits and limitations. To date, however, no single classification scheme has been widely adopted by the international bibliometric community. In light of these factors, the classification presented here—featuring a hierarchical, three-level classification tree—was developed based on best-practice taxonomies. Categories were modelled on those of existing journal classifications (ISI, CHI, ERA), and their groupings of journals acted as “seeds” or attractors for journals in the new classification. Individual journals were assigned to single, mutually exclusive categories via a hybrid approach combining algorithmic methods and expert judgment. Notably, the classification was designed to be as inclusive as possible of newer fields of inquiry; general and multidisciplinary journals; and the range of arts and humanities disciplines.

The classification is freely available under a creative commons license and is operational in 26 languages. Science-Metrix encourages the use of this tool in any research, education and librarianship endeavours. Furthermore, feedback is considered essential to the continued improvement of the classification and is always welcome.
